Why is lipid solubility an important characteristic of local anesthetic drugs?

Question

Quizplus · Accepted Answer

A) A greater lipid solubility enhances the diffusion of the anesthetic drug through the nerve, allowing for a faster onset of action and a larger area of anesthesia.
B) A greater lipid solubility alone does not necessarily indicate a higher potency of the anesthetic drug, but it can contribute to a more effective anesthesia.
C) A greater lipid solubility allows for a lower effective dose of the local anesthetic drug, which can reduce the risk of toxicity and side effects.
